I just published an app that supports these devices, starting with the Temperature & Humidity sensor.
It looks like every White label company have their own string after the producent ID but I have not been able to test more than one device of each kind so this can be interesting to handle.

The white label I made the app for is the Nordic company Malmbergs but seeing this I might change that to a general Tuya Zigbee app instead.

Edit: There is now a Tuya Zigbee app in the App store, every White Label Brand have a specific manufacturername that needs to be added to the app. So if your device does not work, post a comment in the thread below.
